RAF Typhoon fighter aircraft have conducted a mission with French aircraft in a combined operation against an underground arms cache in Syria used by the Daesh militant organization, per a report from the British defence ministry.
The site, pinpointed through reconnaissance, was thought to be housing weapons and explosive materials, the statement said, and was located in mountainous terrain just above Palmyra in the heart of Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to strike a several approach shafts providing entry to the depot... preliminary assessments suggest the objective was successfully hit," the ministry announced.
There was no evidence of any civilian impact in the strike late on Saturday and each participating jet made a safe return, the defence officials confirmed.
The British jets were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as ISIS - established extremist governance over parts of Iraq and Syria until 2019.
"This strike shows the UK's leading role, and commitment to operate in unison with allied nations, to stamp out any revival of IS and their violent and radical beliefs in the Middle East," UK Defence Secretary the Defence Secretary stated.
RAF aircraft have performed patrols over Syria to "deter any attempted comeback" of Islamic State following its defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank all the members of British forces who took part in this mission for their expertise and their courage," Healey added. "They were among thousands of British troops deployed over the festive period. This mission, to take out terrorist threats who pose a risk to our safety, shows how UK forces are always on standby, all year round, ensuring Britain's security within its borders and influential overseas."
In December, the American forces carried out what it described as a "massive strike" against Daesh sites in Syria, subsequent to an ambush claimed the lives of two American soldiers and a civilian linguist in the Palmyra area.
The United Nations reports Islamic State still boasts roughly 5-7 thousand fighters in Iraq and Syria.
